Perithecia scattered, depressed-globose, 150-300 ji diain., buried, 

 but raising the epidermis into strong, hemispherical protuberances, 

 finally deciduous. Ostiolum subglobose-papillate, ijlack, rough, erum- 

 pent. Asci clavate, attenuate-stipitate, 90-100 x 1 2 /i, parapliysate. 

 Sporidia biseriate, fusoid or clavate-fusoid, 20-25 x 4-5 /i, endochrome 

 4-6-parted, mostly 5-parted, })ale yellow. 



On dead stems of Juncus, lona, N. J. 



The sporidia ai'e at first surrounded with a broad, gelatinous 

 envelope which disappears together with the bristle-like apical appen- 

 dage. The measurements here given apply to the body of the sporid- 

 ium and do not include the envelope. Specc. of L. apogon, S. & S. 

 in Kriegers Sax. Fungi, 130, are quits different from this. L. juncina, 

 Awd. (Myc. March. 2140) has much smaller and less prominent peri- 

 thecia.

 MetasphcEria hyalospora^ Sacc. Syll. 3497, Cke. Syn. 4495, 

 Kxsicc. BU. N. A. F. 587. 



Perithecia gregarious but separate, erumpent-superficial, rather 

 less than \ mm. diam., globose, black. Ostiolum rather acutely coni- 

 cal, becoming narrowly perforated. Asci densely fasciculate, cylin- 

 dric-subclavate, 90-100x10-12 jx, often flexuous, 8 spored, with a 

 short, nodulose stipe, and with filiform paraphyses. Sporidia fusoid, 

 28-32 X 5|-6J //, obtusely acuminate at each end, somewhat curved, 

 8-guttulate, then torulose, 7-septate, hyaline. 



On decaying stalks of Zea Mays and on culms of Panicum cru's- 

 gain, Newfield, N. J., and oa Sabal Palmetto, Louisiana (Langlois). 



Both the New Jersey and Louisiana specc. have the sporidia 35- 

 45x7-9 fx, 9-12-septate and slightly curved.

Scattered, covered or erumpent and semiimmersed, black. Asci 

 clavate, sessile. Sporidia fusoid, hyaline, 3-5-septate, 22-25 x 5 /.t.
